Carbon Nanoflakes and Carbon Nanowalls: An innovation in Biosensors

Abstract

Over the last couple of years, graphene and other related materials such as carbon nanowalls (CNWs) and carbon nanoflakes (CNFs) have become a very important research subject in microelectronics. The use of these two carbon-based materials in biosensor research is not yet explored. But carbon nanotubes (CNT), a related material, are already being pursued as a possible material to use in biosensors Carbon-based materials with SNP sensitivity have already been used to create ssDNA biosensors. But the fabrication of nano crystalline diamond (NCD) is expensive, and not possible on a large scale, which will be a possibility for graphene and CNFs. The physical properties of CNWs and CNFs may make it possible to develop a more sensitive sensor that will require less ssDNA material and will produce more stable measurements. In the first stage of the research, ssDNA was covalently bonded to the CNWs. Since CNWs and diamond are all made of carbon, the method developed by P. Christiaen
